Not Cool! Mariah Carey Is SEETHING After Learning About Nick Cannon's New Baby Mama

Baby news should be exciting for everyone, but that allegedly wasn't the case for Mariah Carey when she heard about Nick Cannon having another baby mama!

A source told InTouch that the diva flipped out after Nick revealed during a radio interview that he got pageant beauty Brittany Bell pregnant and they're having a child together.

"Mariah isn't taking any of Nick's calls right now," said the source.

It doesn't help matters that she found out "just before the rest of the world," which left her in "total shock," added the source.

But Mariah really shouldn't be too upset, considering she was spotted making out with her backup dancer Bryan Tanaka in Hawaii recently!
